STOVE.

Specicaton of Letters Patent No. 28,418, dated March 29, 1859.

To all whom 'Lt may concern:

Be it known that I, T. J. IVHITEHEAD, of South Paris, in the county of Oxford and State of Maine, hav-e invented a new and useful In'iprovement in Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure lis a vertical longitudinal section of a stove adapted for using my improvement.

advantageously during winter weather. Fig. 2, is a plan or top view of a stove adapted for using my improvement during the warm weather. Fig. 3, is a vertical longitudinal section of the same.

Similar letters of reference, in each of the several figures, indicate corresponding parts.

My invention consists in the combination with the fire chamber` which has conveniences on top for receiving boilers, kettles, pans &c. and an oven having hollow walls, filled in with some non-conducting material, of a removable fire chamber casing which has hollow walls filled in with some nonconducting material and is in shape, externally, nearly the counterpart of the fire chamber and serves for incasing the whole of the exposed portion of the tire chamber. and at the same time allows acc-ess to the holes in the top of the fire chamber and to the fuel door thereof, whereby in warm weather the operations of baking, boiling, &c., can be carried on with great economy of fuel, in a room, without the necessity of removing the fire chamber casing, or of any inconvenience from the radiation of heat, being experienced, either from the oven or fire chamber; and whereby in cold weather the room in which the oven is located can be heated to the desired degree and the necessary boiling or other similar cooking operav tions carried on without any considerable heat being radiated by the cooking oven.

To enable others, skilled in the art, to

make and use my invention, I will proceed to describe its construction and operation.

A, represents an oven of ordinary con struction, either square or round, constructed so as to receive a suitable non-conducting material within its hollow walls as shown at B, C, D, E, F. The non-'conducting materials which I prefer to employ are of light colored oxids, or earths, to wit; oxid of calcium, of alumina, potassium, silex, &c.; these materials being used separately or by mixing two or more together so that the lighter colored material shall predominate. In the front of the oven, an opening a, is formed and through this opening, the rear extension or flue F, of a fire chamber or stove G, is passed as shown. The extension F, connects with a vert-ical pipe H, passed down through the top of the oven, as shown. The body or main portion of the lire chamber stands out in the room in front of the oven, and is of the form shown in the drawing or in any other lnore suitable shape, being furnished at one end with a fuel and draft door I, and with'holes Z), b, in its top for the reception of pots, kettles, griddles, &c., as shown in Fig. 1, said holes being furnished with covers when cooking is not being performed. The arrangement thus described answers for winter use. Now to render this arrangement more liseful and agreeable in the summer season, I arrange around the fire chamber as shown in black in Fig. 3, and red in Fig. 2, a removable casing J, with double walls, having a suitable or light colored nonconducting material c, placed between them. This casing has holes b', in its top, similar to those 7), with the exception of their being enlarged so as to allow the pots, kettles, &c., to rest upon the top of the re box over the openings in the same, as shown in Fig. 3. The openings in this casing are furnished with non-conducting covers d.

In practice it may be found advantageous to white wash the interior of the oven with a solution of alum, lime and glue so as to more eifectually prevent the radiation of the heat back into the oven, this, however, may not be essential as I have found by experiment that the outer walls of the oven remain almost perfectly cold during a long period while baking is being rapidly performed in the inside of the oven, by simply employing the light colored non-conducting materials herein named between the walls, these materials by a well known principle preventing a rapid radiation of the heat.

In practicing with my invention, it is found that a great economy of heat and consequently fuel is effected in the winter season and by attaching a conducting or radiating drum or pipe above the oven the escape or waste heat can be thrown into regulating` the heat, but as these devices arejcommon to all stoves, no particular description of them is deemed necessary.

The novelty and gist of my invention lies in the removable fire chamber casing used in combination With an oven and fire chamber in the manner herein described and shown, so that cooking can be performed over the fire chamber While the casing is applied. Therefore That I claim as my invention and desire to secure by Letters Patent, is*

The combination With the re chamber described, and With an oven having hollovtr walls filled in with nonconducting material, of a removable fire chamber casing which has hollow Walls filled in With a nonconducting material, and is in shape, eX- ternally, nearly the counterpart of the fire chamber, and serves for incasing the Whole of the exposed portion of the fire chamber, and at the same time allows Yaccess to the holes in the top of the fire chamber and to the fuel door thereof, substantially as and for the purposes set forth.
